The rate of change of the inertia tensor is defined by the following equation. ˙I=⎡⎢⎢⎢⎢⎣˙Ixx−˙Iyx−˙Izx−˙Ixy˙Iyy−˙Izy−˙Ixz−˙Iyz˙Izz⎤⎥⎥⎥⎥⎦ The integration of the rate of change of the quaternion vector is given below. ⎡⎢...
This assumption leads to slightly larger contributions from short-range correlations than with further propagation to the second propagation step between discontinuous glaciers (equation (6)). Uncertainties are largely dominated by short- to long-range spatial correlations. d, Comparison of specific-...
Around a million quasars have been catalogued in the Universe by probing deeper and using new methods for discovery. However, the hardest ones to find seem to be the rarest and brightest specimens. Here we study the properties of the most luminous of all
Since a rocket-propelled spacecraft in free flight derives its only acceleration from discharge of propellant mass, its equation of motion follows directly from conservation of the total momentum of the spacecraft and its exhaust stream: (1)mυ.=m.υe, where m is the mass of the spacecraft...
By solving the equation of radiative transfer in extended atmospheres, we construct a semiempirical model for a WN5 star (M WN5=10M ⊙)) with a helium core and an expanding envelope, whose physical and geometric parameters are known mainly from light-curve solution for the eclipsing binary V...
Secondary ion mass spectrometry (SIMS) is a sophisticated and powerful analytical technique to characterise the surface and sub-surface of materials. It ha
, 1997). The region between the outflows and jets and the disk may be subject to strong magnetic fields that focus the flow of incoming material from the disk as it is being accreted onto the star and then project it back across the disk. These “X-winds” then produce a conveyor ...
(2023b) applied the Tikhonov regularization with a single regularization parameter for each observation equation (Tikhonov, 1963a, 1963b). The multiple parameter regularization can effectively balance signal retention and noise suppression across various spectral domains, outperforming the commonly used ...
such as assisted evolution which aims to boost population resilience by propagating more heat tolerant corals through selective breeding or assisted geneflow43,44. Furthermore, protecting reefs with higher levels of coral bleaching resistance to promote natural reseeding with tolerant larvae could also ...
Across the Antarctic ice sheet, the temperature at the ice-bed interface – basal temperature – is critical in maintaining the ice sheet’s configuration through its influence on basal sliding, subglacial hydrology, and ice-flow regime1,2,3,4. While frozen bed conditions beneath the continental...
